He has a NMC. I highly doubt he would want to come to Ottawa. I could see something like Miller for Kreider, but Kreider as a base probably has Vancouver on his list.
Maybe something like Miller, and Hoglander for Kreider, Kakko as a base, and then NYR send VAN picks and prospects to compensate for the downgrade.
Unless they want futures, in which case the return is probably something really polite like a late 1st, a team's fourth best prospect, and maybe a 2nd or 3rd round pick. Players with NMCs, even great ones, rarely get big returns unless they really play ball.
